Application filed April 6,` 1925. Serial No. 21,012.

This invention relates to hinges and has special reference to a hinge which permits a relative sliding and turning movement-bef tween the bodies `to which it is attached. The particular use to which this hinge is intended to bel applied is as a connection between afil'ler leafA for extension4 tables and the twol sections of the table -top between which the V'ller leaf is mounted. j

The objects of the vide suchl a hinge whichA willA support the filler leafA from the table top in such manner asto. permit the filler leaf to bein the same plane as and between the two sections and which will permit the table tops to opened wide enough to permit the usual dowel pins to be used between the table top parts and the filler leaf. Further 'objectsy 3Q are to provide'a hinge which is cheap to make and to apply; easy to operate; effec tive in use; and which will not easily get out of order or repair.

I attai these and other objects by the devices, mechanisms and arrangeii'ients illustrated in the accompanying drawings, in

which-1 Y Fig. l is a cross-section of a table top in closed position, showing two of my hinges in position thereon; Fig. 2 shows the parts in the positions occupied when the table is p'artway opened; Fig. 3, when fully opened.

and the ller leaf still in stowed away posi-f tion; Fig. 4, when the fillei-,leaf is raised;l

andFig. 5, when the table top sections are closed thereon' to 'form an extended table; Fig. 6 is a plan view of the sliding plates forming'one hinge; Fig. T is a cross-section of the end of the guide which is secured to awlongitudinal section thereof, to show the stop at the end thereof.

Similar numerals of reference refer to similar parts throughout the several views, sa The operation of the table will first be briefly described; The table comprises two invention are to pro-v of the table top orl to be, swung thereunder will allow; which isslid# the vunder sideof the table top; and Fig. 8 iS top sections 1 and 2, suitably supported and i slidably connected vtogether in the usual inannei andk each provided with suitable vertical y y aprons 3. The filler leaf ispreferahtly made with two pieces 4 and' 5 divided longitudinally of the table, that is to say at right angles to the, joint between the'twopaits 1 and 2 ofthe enedj together by hinges or -other-meai is which Vare not illustrated herein as they `form -no part of this invention. The part 4 is fastened to the table tops l and v2, by. a pair table top, and suitably'fast'- r of my improved hinges, hereinafter "dei scribed, and thepart 5 lies below it when in stowed position (Fi-gal, 2 andland,v in the samel plane when in extended position (Figs. 4 and 5). Dowel `pins 6 extend. from one table topV section 2 andr enter holes 'inv the other section l, lor inthe filler leaves l and 5, while 'similar` dowel lpins 7 entendvr from l @QllGSiDOndng points in. the filler-.leaves 4 and 5 and enter the, samel holes. in said table ton Section 1. I y f Referring, new, to Fig. 1 itwill bey seen that the width of the fillerleaves 4 andf, together with their VdOWel pins 7 fill up the entiiewidth of the space between the apronsk 3, when stowed away and the table is in closed poSl tion. vAlso, referring to Figs.

which 'the dowel pins 6 and 7 extend from 3 and 4 vit will be seent'hatthe tabletop secbesepaifalted from each their respective surfaces, therefore their movement apart must be greater 'than the distance between the aprons 3 by more than the length of the dowels 6. But, since the total length of the two hereinafter described guides, which are securedfto the under sides of the table top sections land l2, must be less `than the distancebetweenl the said aprons 3 and, since it is also necessary that the plates in said. guides a have .some effective length in ad lition, itis evident that lthe hingeplates lmust also slide ron -the filler leaves to allow for the extra `distance which the table top sections move, and this is the condition which this .form of hinge is es; pecially designedt'o fulfill.

Referringnext to the rhinge itself, it will be first understood thatusually two of these hinges will beused,`said hingesv being coaiiially located turi'ied .to pcciipy ecrire-l spondingly reversed positions. One only made much' such hinge will therefore be described. On the under side of the table top section 1 is secured a guide plate 8 whose. axis is at right angles to the joint between the table top sections 1 and 2. This plate 8 extends from the apron 3 practically to the center lineV of the table, and is provided with two downand-in turned flanges 9 which support the sliding hinge plate and which are separated by a suflicient space to permit the hinge lug to pass freely between them. These flanges 9 extend from end to end of the plate 8 and y described stops 10. The plates Sand 11 may of the guides.

be secured in place by means of screws or any other desired means, provided that the headsthereof do not interfere with the free movement of the hinge plates in the channels VEach hinge. proper `,is in two sections, a short section 12 adapted to engage the guide 8-and to be supported thereby, and a long section 13 adapted to engage the guide 11 and to be supported thereby. Each such section'12and 13 comprises a straight plate which lhas a downturned ear or lug 14 and 15, respectively, oted together by passing through them. 13 are cut at their adjacent endsto form shoulders 17 and to permit the lugs 14 and 15 to pass between the flanges 9 on the respective guides 8 or11. The shoulders 17 and these two lugs are piv- The plates 12 and on the plate 12 are adapted to engage the stops 10 on the guide 8. The plate 13 is providedl Awith a central elongated slot 18V Vwith closed ends 19 and 20,- andwith a narrow tail lug 21 which is bent down therefrom and provided with a suitable hole for the spring 22, hereinafter described.

The plate 12 isV mounted in the. guide 8 with its lug 14 towards Vthe center of the table, and the plate 13 is mounted in the guidell. A stop pin 23 is passed through the slot 18 and into the filler leaf 4 in such position that when the table is closed (Fig.

1) the stop 23 will engage the inner end 19 of the slot 18 and, in this position, the end of the plate 12 is at the eXtreme end of the guide 8 and practically'touching the apron 3. `Also, in this position, the plate 13 has been slid back over the filler leaf, away from the joint, so that leaf, or the ends of its dowels 7, practically touch `th@J same apron 3 and are thus subs out of their supporting means of the hinge pin 1G theedge of the filler b l thereof (Fig. 2) so that, in this position, the I hinge plates prevent the further separation of the table top sections through the engagement of the stop lugs 10 with the shoulders 17 and the stop pins 23 with the slot ends 20'. In this position, therefore, the plates 12 have slid the length of the guides 8, as far .as thestops 10 will permit them, and the plates 13 have slid the length of the'slots 18. The stop 10 and shoulder 17 are so positioned as to permit the hinge lug 14 to extend slightly beyond the plane of the edge of the table section, thuspermitting the corners of the plate 13 to pass the edge of the table top without scratching it. This effect is further insured by means ofthe springs 22 secured to the lugs 21 and to suitable pins 24 in the filler leaf 4 to pull the said hinge plates towards the center of theliller leaf. V

rllhus it will be seen that my improved greater movement of the hinge permits of a l table tops thanthe combined length of the slides 8,on the under sides thereof, by permitting the hinge to float between the parts hinged together'thereby; and by limiting the extent of such floating movement it prevents the table from being opened wide enough to drop the filler leave-s by allowing the oating hinge parts to vbe pulled guides. It will also be observed that the filler leaf is permanently attached to the table; that it is suspended byk substantial means at a predetermined distance below the table top when not in use; that the nently attached to each hinged part and yet floats therebetween; that each hinge comprises a pair of flat vplates mounted on the under sides of the hinged parts; and that each such plate is provided with an ear which cooperates with the corresponding ear of the other plate to form the lholder forV described my invention,

together, comprising ahinge platevslidably.

mounted' on one body; hinge plate slidably body; and a hinge a complementary mounted on the other pivot pin connecting both said plates together, whereby said two oc ies are secured together and one body is permitted aeslidable and revoluble movement with relation to the other body.

from the. undersurfaces of hinges A, are perma-A` mentary lug extending therefrom; and a pivot pin connecting both saidlugs to hinge the plates together, whereby said two bodies are secured together and one body is permitted a slidable and revoluble movement ,with relation to the other body.

3. A hinge adapted to secure two bodies together, comprising two separate guide plates each tixedly secured to one of said Vbodies in axial alinement with each other;

together with a floating hinge Comprising two parts pivotally secured together and each part slidably mounted on one of said y guide plates whereby the two bodies are secured together in slidable and revoluble relation.

4. A hinge adapted to secure two bodies together, comprising two separate guide plates each iixedly 'secured to'one of said bodies in axial alinement with each other; a pair of separate complementary hinge plates, each slidably supported in one said guide plate, each having Complementary hinge lugs extending'at right-angles thereto; and a pivot pin passing through both said lugs, whereby vthe two hinge plates form a hinge body iioating in said' guide plates,

and whereby the two bodies are secured to-` gether in simultaneously slidable and revoluble relation.
